A36 hot rolled steel flat bars are manufactured in accordance with the ASTM A36 specification for carbon structural steel. These flat bars are ideal for a wide range of fabrication and construction applications due to their excellent weldability, machinability, and formability. Featuring a rough, blue-grey surface with slightly rounded edges, they may have minor dimensional variances along their length. As a type of low carbon mild steel, A36 flat bars offer reliable strength and long-term durability. Common uses include brackets, supports, frames, trim, sculptures, and general structural components.
